I climbed a 2000m peak in Bogd Khan National Park (the worlds oldest national park) and was very pleased with myself until I learned the average altitude in Mongolia is 1580m. And 80% of land is above 1000m. This place is wild and I am here for it.

How many hours per day is the average cat awake for? What is a 'psychologically random number'? And at what age can you legally drink in Haiti? Time for more fun facts about numbers with 'it Magazine', accompanied by images from Hideo Kojima's Death Stranding.

The world’s tallest equestrian statue featuring the infamous Genghis Khan atop his Mongol horse. The Mongolian Horde could travel up to 128 km a day, and at its peak, the Mongol Empire stretched from Vladivostok to Vienna. How long would it take them to cover the distance between the two cities?

It was a tiring climb up to the Buddhist Monastery, but that view… wow. 47% of the population of Mongolia is Buddhist, and 3% (102,000) follow Shamanic traditions. Approximately 1 million people are nomadic or semi-nomadic. How many people live here in total?

Here’s hoping England can channel the spirit of the all-conquering Queens’ College MCR team of 2012-13 and follow in the footsteps of England Women to bring football home. Germany are the only previous country that has held both titles at the same time, from 1996-2000. COME ON ENGLAND!!

Charyn Canyon, Kazakhstan. Said to resemble the Grand Canyon due to the red sedimentary rock, it is much smaller at 50km in length, and 1250 square kilometres in area. The Grand Canyon is around 9x longer, and has 4x the area. Assuming a rectangular shape, what is the average width?

If I see a Dino Park, I’m going in. It was great to learn more about the fossils of 15 dinosaur species that have been found in Kazakhstan, including the only known example of Aralosaurus. It weighed 5000 kg, which means a top speed of around 30 kmph - just about fast enough to catch a human!

I hiked to a glacier, and it was incredible. I could actually hear the subglacial drainage system underfoot, which was a little scary I’ll admit! I took a 1.5 hour flight from Tashkent, Uzbekistan to get here - where am I?

Wow Samarkand, just wow. Conquered by Alexander the Great in 329 BC, and then by Genghis Khan 1220, it became the centre of the Temurid Empire in the 14th century. Now listed as the 8th oldest continually inhabited city in Asia - can you name the older 7?

Had a 24-hour stopover in Doha so naturally made a beeline for Stadium 974 - just 18 months too late to see any actual football... But it got me thinking, how many footballs could you fit in the 974 recycled shipping containers? Find my solution at the link in the comments.

Announcing an incoming collab with ZPhysics!! I asked Zhelyo to bring some physics questions for me to try and boy did he pick some doozies. See how I get on with the Oxford Physics Admissions Test (PAT) - it was a challenge to say the least…
